This came up again for the nth time, as I hear at various discussions and debates at various places including the internet. But as always there is learning (at least for me) for the taking. Here is a nice and cute summary on the Bayesian philosophy, drafted Radford Neal . Ah, the latest revisit to this Bayesian versus Non Bayesian came up when I was chatting with a Finance friend. I cannot divulge the details of the conversation here, but I thought of writing a bit about the Bayesian inference, which to me is always the formal and correct statistical method (I must admit that, I am somewhat novice to have a strong counter argument, which is tame, but frankly I need to learn more!)
